Problems solved by technology
[0003] In the prior art, usually only one authentication key is set in the charging device. When the validity of the authentication key is judged, if the judgment result is invalid, the charging device cannot realize fast charging with the terminal device, or even Can't charge normally
[0004] This has just led to the waste of resources on the charging equipment during the charging process in the prior art, increasing the charging cost

The invention provides an authentication method and an authentication device of a connecting device and the connecting device, and belongs to the technical field of charging authentication. The method comprises the following steps: sending authentication information of a first authentication key to terminal equipment electrically connected with a connecting device, so that the terminal equipment performs validity authentication of the key based on the authentication information of the first authentication key; determining a secret key authentication result sent by the terminal equipment, wherein the secret key authentication result comprises that the secret key is valid and the secret key is invalid; if the secret key authentication result is that the secret key is invalid, authentication information of at least one second authentication secret key is sent to the terminal equipment, so that the terminal equipment performs validity authentication of the secret key based on the authentication information of the second authentication secret key until the secret key authentication result of the second authentication secret key is that the secret key is valid, and the second authentication secret key is used as a target authentication secret key; and performing protocol authentication according to the target authentication key. According to the invention, the switching of the authentication key can be realized, and the waste of resources is avoided.
Description
technical field [0001] The present application relates to the technical field of charging authentication, and in particular, to an authentication method for a connection device, an authentication device, and a connection device. Background technique [0002] Charging authentication is a protocol authentication process based on whether fast charging can be achieved between charging devices (such as charging cables, wireless charging devices, etc.) and terminal devices (such as mobile phones, tablet computers, etc.). The authentication key is valid. [0003] In the prior art, only one authentication key is usually set in the charging device. When the validity of the authentication key is determined, if the determination result is invalid, the charging device cannot realize fast charging with the terminal device, or even Cannot charge normally. [0004] This leads to the waste of resources of the charging equipment during the charging process in the prior art, and increases t...
